To examine the phenology, disease resistance and standing power of new wheat germplasm sown on 20 April versus control varieties.
ï‚· Stripe rust (Puccinia striiformis f. sp. tritici) was the most destructive disease in the untreated screen, severely affecting Catapult, Rockstar, and Trojan (93%, 65%, and 35% plot infection respectively).
ï‚· From sampling carried out the 239 pathotype was the dominant pathotype on site with lower levels of the 198 pathotype (the dominant pathotype in 2020).
ï‚· Septoria tritici blotch (STB) caused by the pathogen Zymoseptoria tritici was more significant in 2021 in terms of green leaf area lost, with up to 75% plot infection in Scepter. Other notable infections include V12167-048, Coota, and L13070-027 (70%-39% plot infection).
ï‚· The following varieties AGFWH004418, AGFWH004618, Big Red (AGFWH004718) and AGFWH004818 had similar phenology, and as good as or better disease resistance and standing power (straw strength) than the highest yielding feed wheats on the research site RGT Accroc, Anapurna and RGT Cesario (see trials 2 – 4).
